Domestic issues are often met with social workers where I'm from. They gain early detection and access, by registering and treating social issues such as poverty, health or mental related issues. A lot of people then have their lives changed for the better, so they never fall into crime. On a whole, this is good for society, since it gets the benefit of less crime and violence, and so society becomes safer. On top of that, our police is trained in peacefully settling most disputes, though they of course retain the monopoly on violence if need be.
